We recently reported on the AMD Ryzen 7 PRO 5750G Zen 3 APU being discovered in China. The Ryzen 7 PRO 5750G engineering samples were distributed to system integrators and OEMs for validation with confidentiality clauses however it seems many have made their way elsewhere with several selling on eBay for 500 USD each. The Ryzen 7 5750G and Ryzen 7 PRO 5750G should be vertically identical in performance as the only differences are mainly software and support based.

The Ryzen 7 PRO 5750G was initially overclocked to 4.89 GHz at 1.5 V however this proved to be unstable so the chip was benchmarked at 4.8 GHz with 1.47 V which proved stable. The APU scored 660 points in the single-core CPU-Z benchmark and 6898 in the multi-core which places it firmly within range of the Ryzen 7 5800X at 663 and 6766 points respectively. Considering that this chip is only an engineering sample it is likely to offer similar performance at stock speeds when officially launched.
